Store is tiny all of a sudden

All of a sudden my pvp.net client has been resetting to the point where it shows the dynamic draft tutorial every time I reopen it. And now my client has made the store small no matter how I change the resolution or the graphics card it runs on. Anyone able to help me with this? p.s. sorry if this is not in the right discussion category Image Link : https://gyazo.com/3219b0537c967b420333dc4435ea2fcf
